PRESENTATION OF FINANCIAL INFORMATION Gruma, S.A.B. de C.V. is a publicly held corporation (Sociedad Anónima Bursátil de Capital Variable) organized under the laws of the United Mexican States, or Mexico. In this Annual Report on Form 20-F, references to pesos or Ps. are to Mexican pesos, and references to U.S. dollars, U.S.$, dollars or $ are to United States dollars. We, our, us, our company, GRUMA and similar expressions refer to Gruma, S.A.B. de C.V. and its consolidated subsidiaries, except when the reference is specifically to Gruma, S.A.B. de C.V. (parent company only) or the context otherwise requires. This Annual Report contains our audited consolidated financial statements as of December 31, 2006 and 2007 and for the years ended December 31, 2005, 2006 and 2007. The financial statements have been audited by PricewaterhouseCoopers, an independent registered public accounting firm. We publish our financial statements in pesos and prepare our consolidated financial statements in accordance with the Normas de Información Financiera (Mexican Financial Reporting Standards or FRS ), which are accounting principles generally accepted in Mexico and are commonly referred to as Mexican FRS. Mexican FRS differs in certain significant respects from accounting principles generally accepted in the United States of America, commonly referred to as U.S. GAAP. See Note 21 to our audited consolidated financial statements for information relating to the nature and effect of such differences and for a quantitative reconciliation of our consolidated net income and stockholders equity to U.S. GAAP. As the Mexican economy experienced significant levels of inflation prior to 2000, we are required under Mexican FRS to recognize the effects of inflation in our financial statements. Under FRS B-10, issued by the Consejo Mexicano para la Investigación y Desarrollo de Normas de Información Financiera, A.C. (Mexican Financial Reporting Standards Board or CINIF ), we are required to present our financial information in inflation-adjusted monetary units to allow for more accurate comparisons of financial line items over time and to mitigate the distortive effects of inflation on our financial statements. Unless otherwise indicated, all financial information in this Annual Report has been restated in pesos of constant purchasing power as of December 31, 2007. We are required to determine our monetary position gain/loss to reflect the effect of inflation on our monetary assets and liabilities. We determine our net monetary position by subtracting our monetary liabilities from our monetary assets and then the resulting net monetary position is multiplied by the appropriate inflation rate for the period with the resulting monetary gain or loss reflected in earnings. In so doing, we can reflect the effect inflation is having on our monetary items. Pursuant to FRS B-15 issued by CINIF, we apply the actual inflation rate in the relevant country of each non- Mexican subsidiary and then translate the inflation-adjusted financial statements into pesos. The figures for subsidiaries in Central America, Venezuela and the United States are restated to period-end constant local currencies following the provisions of FRS B-10 and B-15, applying the general consumer price index from the country in which the subsidiary operates. Once figures are restated, they are converted to Mexican Pesos by applying the exchange rate in effect at the end of the period. For the purposes of the quantitative reconciliation to U.S. GAAP, we have restated the data as of December 31, 2006 and for years ended December 31, 2005 and 2006 in pesos of constant purchasing power as of December 31, 2007 using the Mexican National Consumer Price Index, or NCPI, rather than the international restatement factor in FRS B-15 of CINIF. For a more detailed discussion of Mexican FRS inflation accounting methodologies, see Item 5. Operating and Financial Review and Prospects Management s Discussion and Analysis of Results of Operations Overview of Accounting Presentation. 3

MARKET SHARE AND OTHER INFORMATION The information contained in this Annual Report regarding our market positions is based primarily on our own estimates and internal analysis. Market position information for the United States is also based on data from the Tortilla Industry Association and ACNielsen. While we believe our internal research and estimates are reliable, they have not been verified by any independent source and we cannot assure you as to their accuracy. All references to tons in this Annual Report refer to metric tons. One metric ton equals 2,204 pounds. Estimates of production capacity contained herein assume operation of the relevant facilities on the basis of 360 days a year on three shifts and assume only regular intervals for required maintenance. FORWARD LOOKING STATEMENTS This Annual Report includes forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, including the statements about our plans, strategies and prospects under Item 4. Information on the Company and Item 5. Operating and Financial Review and Prospects. Some of these statements contain words such as believe, expect, intend, anticipate, estimate, strategy, plans and other similar words. Although we believe that our plans, intentions and expectations as reflected in or suggested by these forward-looking statements are reasonable, we cannot assure you that these plans, intentions or expectations will be achieved. Actual results could differ materially from the forward-looking statements as a result of risks, uncertainties and other factors discussed in Item 3. Key Information Risk Factors, Item 4. Information on the Company, Item 5. Operating and Financial Review and Prospects and Item 11. Quantitative and Qualitative Disclosures About Market Risk. These risks, uncertainties and factors include: general economic and business conditions, including changes in exchange rates, and conditions that affect the price and availability of corn, wheat and edible oils; potential changes in demand for our products; price and product competition; and other factors discussed herein. 4

PART I ITEM 1. Identity of Directors, Senior Management and Advisors. Not applicable. ITEM 2. Offer Statistics and Expected Timetable. Not applicable. ITEM 3. Key Information. SELECTED FINANCIAL DATA The following tables present our selected consolidated financial data as of and for each of the years indicated. The data as of December 31, 2006 and 2007 and for the years ended December 31, 2005, 2006 and 2007 are derived from and should be read together with our financial statements included herein and Item 5. Operating and Financial Review and Prospects. Our consolidated financial statements are prepared in accordance with Mexican FRS, which differs in certain significant respects from U.S. GAAP. Note 21 to our audited consolidated financial statements provides information relating to the nature and effect of such differences, as they relate to us, and provides a reconciliation to U.S. GAAP of majority net income and total stockholders equity. Pursuant to Mexican FRS, the consolidated financial statements and the selected consolidated financial data set forth below restate the components of stockholders equity using the NCPI factors and record gains and losses in purchasing power from holding monetary assets or liabilities. Under Mexican FRS, non-monetary assets, with the exception of inventories and fixed assets of non-mexican origin, are restated using the NCPI and General Consumer Price Index, or GCPI, factors for foreign subsidiaries. Inventories are restated at current replacement costs while fixed assets of foreign origin are restated by the inflation rate of the country of origin prior to translation to pesos at the period-end exchange rate. Mexican FRS also requires restatement of all financial statements to pesos of constant purchasing power as of the date of the most recent balance sheet presented, and accordingly all data in the consolidated financial statements and in the selected consolidated financial data set forth below have been restated in pesos of constant purchasing power as of December 31, 2007. The effects of inflation accounting under Mexican FRS, other than for the use of a specific index for the restatement of fixed assets of foreign origin, have not been reversed in the reconciliation to U.S. GAAP. See Note 21 to our consolidated financial statements. 5

(4) Net of intercompany transactions. (5) Includes 194 thousand tons of temporarily idled production capacity at December 31, 2007. (6) Includes 118 thousand tons of temporarily idled production capacity at December 31, 2007. Dividends Our ability to pay dividends is limited by Mexican law, our estatutos sociales, or bylaws, and by financial covenants contained in some of our credit agreements. Because we are a holding company with no significant operations of our own, we have distributable profits to pay dividends to the extent that we receive dividends from our subsidiaries. Accordingly, there can be no assurance that we will pay dividends or of the amount of any such dividends. Pursuant to Mexican law and our bylaws, the declaration, amount and payment of dividends are determined by a majority vote of the holders of the outstanding shares represented at a duly convened shareholders meeting. The amount of any future dividend would depend on, among other things, operating results, financial condition, cash requirements, losses for prior fiscal years, future prospects, the extent to which debt obligations impose restrictions on dividends and other factors deemed relevant by the board of directors and the shareholders. In addition, under Mexican law, companies may only pay dividends: from earnings included in year-end financial statements that are approved by shareholders at a duly convened meeting; after any existing losses applicable to prior years have been made up or absorbed into capital; after at least 5% of net profits for the relevant fiscal year have been allocated to a legal reserve until the amount of the reserve equals 20% of a company s paid-in capital stock; and after shareholders have approved the payment of the relevant dividends at a duly convened meeting. Holders of our American Depositary Receipts, or ADRs, on the applicable record date are entitled to receive dividends declared on the shares represented by American Depositary Shares, or ADSs, evidenced by such ADRs. The depositary will fix a record date for the holders of ADRs in respect of each dividend distribution. We pay dividends in pesos and holders of ADSs will receive dividends in U.S. dollars (after conversion by the depositary from pesos, if not then restricted under applicable law) net of the fees, expenses, taxes and governmental charges payable by holders under the laws of Mexico and the terms of the deposit agreement. The ability of our subsidiaries to make distributions to us is limited by the laws of each country in which they were incorporated and by their constitutive documents. For example, our ability to repatriate dividends from Gruma Venezuela may be adversely affected by exchange controls and other recent events. See Item 3. Risk Factors Risks Related to Venezuela Venezuela Presents Significant Economic Uncertainty and Political Risk. In the particular case of Gruma Corporation, our principal U.S. subsidiary, its ability to pay dividends is subject to financial covenants contained in some of its debt and lease agreements, including covenants which limit the amount of dividend payments. Upon the occurrence of any default or event of default under these credit and lease agreements, Gruma Corporation generally is prohibited from making any dividend or other payments. See Item 5. Operating and Financial Review and Prospects Liquidity and Capital Resources Indebtedness. During 2007, 2006, 2005 and 2004, we paid dividends to shareholders, in nominal terms, of Ps. 410 million, Ps.410 million, Ps.359 million, and Ps.315 million, respectively. In pesos of constant purchasing power as of December 31, 2007, the dividends paid or payable to shareholders in 2007, 2006, 2005 and 2004 amounted to Ps.424 million, Ps.440 million, Ps.396 million and Ps.364 million, respectively. 8

Exchange Rate Information Mexico has had a free market for foreign exchange since 1991. Prior to December 1994, the Banco de México, or Mexican Central Bank, kept the peso-u.s. dollar exchange rate within a range prescribed by the government through intervention in the foreign exchange market. In December 1994, the government suspended intervention by the Mexican Central Bank and allowed the peso to float freely against the U.S. dollar. The peso declined during the period from 1994 through 1998, at times in response to events outside of Mexico, but was relatively stable in 1999, 2000 and 2001. In late 2001 and early 2002, the Mexican peso appreciated considerably against the U.S. dollar and, more strongly, against other foreign currencies. From the second quarter of 2002 and until the end of 2003, the Mexican peso depreciated in value. From the beginning of 2004 to June 2008, the Mexican peso has been relatively stable, ranging from 10.32 to 11.60. There can be no assurance that the government will maintain its current policies with regard to the peso or that the peso will not depreciate or appreciate in the future. The following table sets forth, for the periods indicated, the high, low, average and period-end noon buying rate in New York City for cable transfers in pesos published by the Federal Reserve Bank of New York, expressed in pesos per U.S. dollar.

Risks Relating to Mexico RISK FACTORS Our Results of Operations Could Be Affected by Economic Conditions in Mexico We are a Mexican company with 44% of our consolidated assets located in Mexico and 33% of our consolidated net sales derived from our Mexican operations as of December 31, 2007. As a result, Mexican economic conditions could impact our results of operations. In the past, Mexico has experienced exchange rate instability and devaluation of the peso as well as high levels of inflation, domestic interest rates, unemployment, negative economic growth and reduced consumer purchasing power. These events resulted in limited liquidity for the Mexican government and local corporations. Civil and political unrest in Venezuela or elsewhere could produce similar results. See Developments in Other Countries Could Adversely Affect the 9

Mexican Economy, the Market Value of our Securities and Our Results of Operations. The Mexican economy grew by 1.3% in 2003, by 4.4% in 2004, by 3.0% in 2005, by 4.8% in 2006, by 3.3% in 2007 and by an annualized rate of 2.6% in the first quarter of 2008. However, if the Mexican economy falls into recession, or if inflation and interest rates increase, consumer purchasing power may decrease and, as a result, demand for our product may decrease. In addition, a recession could affect our operations to the extent we are unable to reduce our costs and expenses in response to falling demand. Our Business Operations Could Be Affected by Government Policies in Mexico The Mexican government has exerted, and continues to exert, significant influence over the Mexican economy. Mexican governmental actions concerning the economy could have a significant effect on Mexican private sector entities, as well as on market conditions, prices and returns on securities of Mexican issuers, including our securities. Mexican presidential and congressional elections took place on July 2, 2006. Felipe Calderón Hinojosa was elected president for the 2006-2012 term. He is the second presidential candidate to be elected from the Partido Acción Nacional, which won for the first time in 2000. No political party in Mexico succeeded in securing a majority in the Congress or Senate. The lack of a majority party in the legislature, the potential lack of alignment between the legislature and the president and any changes that result from the presidential and congressional elections could result in instability or deadlock, and prevent the timely implementation of political and economic reforms, which in turn could have a material adverse effect on Mexican economic policy and on our business. Governmental policies have negatively affected our sales of corn flour in the past and may continue to do so in the future. Until 2007 we depended on corn import permits to ensure an adequate supply of corn in low-corn producing regions of Mexico. Commencing on January 1, 2008 pursuant to the NAFTA agreement, the import of grains, including corn, no longer requires import permits. Nevertheless, we cannot assure that the Mexican government will continue to comply with the terms of the NAFTA agreement, nor take actions that could adversely affect us. See Item 4. Information on the Company Regulation. The Mexican government supports the commercialization of corn for Mexican corn growers through the Agricultural Incentives and Services Agency (Apoyos y Servicios a la Comercialización Agropecuaria, or ASERCA). To the extent that this or other similar programs are cancelled by the Mexican government, we may be required to incur additional costs in purchasing corn for our operations, and therefore we may need to increase the prices of our products to reflect such additional costs. See Item 4. Information on the Company Regulation. Since the end of 2006 and continuing through 2007 and 2008, the price of corn set by the Chicago Board of Trade and the average price of Mexican corn increased dramatically due to a number of factors, including the increased use of corn in the manufacture of ethanol, a substitute for gasoline, as well as other bio-fuels. Consequently, the price of corn flour and corn tortillas, the main food staple in Mexico, increased due to such increases in the international and domestic prices of corn. In order to stabilize the price of tortillas and provide Mexican families with a consistent supply of corn, corn flour and tortillas at a reasonable price, the Mexican government promoted two agreements among the various parties involved in the corn-corn flour-tortilla production chain. The first agreement was effective from January 15, 2007 through April 30, 2007. On April 25, 2007, the Mexican government announced a second agreement that extended the provisions of the first agreement through August 15, 2007. As a result, our corn flour prices did not reflect the increase in the cost of corn, which resulted in a significant deterioration in the financial performance of GIMSA, our subsidiary engaged in corn-flour production in Mexico, during the first quarter of 2007. The term of the second agreement was extended subsequently through December 31, 2007. Although the second agreement expired at the end of 2007, as of June 13, 2008, the parties to that agreement have voluntarily continued to operate under its terms. In addition, the Mexican government has recently announced a new policy aimed at aiding the domestic economy in facing the worldwide increase in food prices. Under this new policy, the Mexican government will (i) facilitate the supply in Mexico of, and access of Mexican consumers to, food at the best prices in the international market, (ii) promote the production of food products and increase the productivity of Mexican farms, and (iii) protect the income and strengthen the financial condition of poor families in Mexico. While the Mexican government has not directly fixed or capped corn flour or 10

tortilla prices, it has strongly encouraged Mexican producers and retailers to voluntarily do so. There can be no assurance that there will not be another extension of the aforementioned agreements, that we will not continue to further comply with their terms after expiration, that any of the parties to these agreements will continue to sell corn flour or tortillas at the prices provided in these agreements, that the Mexican government will not reestablish taxes on the import of corn and wheat, or that the Mexican government will not institute price controls or other actions on the products we sell, which could adversely affect our financial condition and results of operations. See Item 4. Information on the Company Business Overview Mexican Operations GIMSA Corn Flour Operation. The level of environmental regulations and enforcement in Mexico has increased in recent years. In the past, the Comisión Nacional del Agua, or National Water Commission or CNA, has brought enforcement proceedings against us for fees arising from alleged water discharges from five of our facilities in Mexico. As of December 5, 2007, all of the proceedings brought against us by the CNA have been resolved in our favor. We cannot assure you that further actions of this type will not be brought against us. We expect the trend toward greater environmental regulation and enforcement to continue and to be accelerated as a result of international agreements between Mexico and the United States. The promulgation of new environmental regulations or higher levels of enforcement may adversely affect us. See Item 8. Financial Information Legal Proceedings and Item 4. Information on the Company Regulation. Devaluations of the Mexican Peso Affect our Financial Performance As of December 31, 2007, 93% of our debt obligations were denominated in U.S. dollars. We generate approximately 49% of our revenues in U.S. dollars, which in 2007 represented 222% of our then outstanding debt obligations. While the dollar revenues we earn may act as a natural hedge for part of our dollar-denominated debt obligations, we have not entered into derivative contracts to hedge our foreign currency risk with respect to the outstanding principal amount of these obligations. However, because we have significant international operations, we remain exposed to foreign exchange risks that could affect our ability to meet our obligations and result in foreign exchange losses on our dollar-denominated obligations. We posted net foreign exchange losses of Ps.56 million in 2005, Ps.19 million in 2006, and gain of Ps.72 million in 2007. Any significant decrease in the value of the peso relative to the U.S. dollar may have an adverse effect on our liquidity and on our ability to meet our dollar-denominated debt obligations. High Levels of Inflation and High Interest Rates in Mexico Could Adversely Affect the Business Climate in Mexico and our Financial Condition and Results of Operations Mexico has experienced high levels of inflation in the past. The annual rate of inflation, as measured by changes in the National Consumer Price Index, was 3.33% for 2005, 4.05% for 2006 and 3.76 for 2007. From January through May 2008, the inflation rate was 1.61%. On June 13, 2008, the 28-day CETES rate was 7.43%. While the substantial part of our debt is dollar-denominated at this time, high interest rates in Mexico may adversely affect the business climate in Mexico generally and our financing costs in the future and thus our financial condition and results of operations. Developments in Other Countries Could Adversely Affect the Mexican Economy, the Market Value of Our Securities and Our Results of Operations The Mexican economy may be, to varying degrees, affected by economic and market conditions in other countries. Although economic conditions in other countries may differ significantly from economic conditions in Mexico, investors reactions to adverse developments in other countries may have an adverse effect on the market value of securities of Mexican issuers. In recent years, economic conditions in Mexico have become increasingly correlated to economic conditions in the United States. Accordingly, the slowing economy in the United States, and the uncertainty of the impact it could have on the general economic conditions in Mexico and the United States could have a significant adverse effect on our businesses and results of operations. See Risks Relating to the United States Unfavorable General Economic Conditions in the United States Could Negatively Impact Our Financial Performance In addition, in the past, economic crises in Asia, Russia, Brazil, Argentina and other emerging market countries adversely affected the Mexican economy. 11

We cannot assure you that the events in other emerging market countries, in the United States or elsewhere will not adversely affect our business, financial condition and results of operations. You May Be Unable to Enforce Judgments Against Us in Mexican Courts We are a Mexican publicly held corporation (Sociedad Anónima Bursátil de Capital Variable). Most of our directors and executive officers are residents of Mexico, and a significant portion of the assets of our directors and executive officers, and a significant portion of our assets, are located in Mexico. You may experience difficulty in effecting service of process upon our company or our directors and executive officers in the United States, or, more generally, outside of Mexico and in enforcing civil judgments of non-mexican courts in Mexico, including judgments predicated on civil liability under U.S. federal securities laws, against us, or our directors and executive officers. We have been advised by our General Counsel, that there is doubt as to the enforceability in original actions in Mexican courts of liabilities predicated solely on the U.S. federal securities laws. Differences Between Mexican FRS and U.S. GAAP May Have an Impact on the Presentation of Our Financial Information Our annual audited consolidated financial statements are prepared in accordance with Mexican FRS, which differ in some significant respects from U.S. GAAP. Financial results reported using Mexican FRS may differ substantially from those results that would have been obtained using U.S. GAAP. We are required, however, to file an annual report on Form 20-F containing financial statements reconciled to U.S. GAAP, although this filing only contains year-end financial statements reconciled to U.S. GAAP for our three most recent fiscal years. See Note 21 to our audited consolidated financial statements. Risks Relating to Our Company Fluctuations in the Cost and Availability of Corn, Wheat and Wheat Flour May Affect Our Financial Performance Our financial performance may be affected by the price and availability of corn, wheat and wheat flour as each raw material represented 33%, 12% and 7%, respectively, of our cost of sales in 2007. Mexican and world markets have experienced periods of either over-supply or shortage of corn and wheat, some of which have caused adverse effects on our results of operations. Recently, there has been substantial volatility and increases in the price of corn, partly due to the demand for corn-based ethanol in the U.S., which has increased our cost of corn and negatively affected our financial condition and results of operation. We believe that the demand for corn will increase over the long term in connection with the manufacture of corn-based ethanol. Also, there have been dramatic increases in the price of wheat driven by negative weather conditions in certain regions of the world and increased demand worldwide, especially from emerging countries. To manage these price risks, we regularly monitor our risk tolerance and evaluate the possibility of using derivative instruments to hedge our exposure to commodity prices. We currently hedge against fluctuations in the costs of corn and wheat using futures and options contracts, but remain exposed to credit-related losses in the event of non-performance by counterparties to the financial instruments. In addition, if corn or wheat prices decrease below the levels specified in our various hedging agreements, we would lose the value of a decline in these prices. Additionally, because of this volatility and price variations, we may not always be able to pass along our increased costs to our customers in the form of price increases. We cannot always predict whether or when shortages or over-supply of corn and wheat will occur. In addition, as described above, future Mexican or other countries governmental actions could affect the price and availability of corn and wheat. Any adverse developments in domestic and international corn and wheat markets could have a material adverse effect upon our business, financial condition, results of operations and prospects. Increases in the Cost of Energy Could Affect Our Profitability We use a significant amount of electricity, natural gas and other energy sources to operate our corn and wheat flour mills and processing ovens for the manufacture of tortillas and related products at our major domestic and international facilities. In addition, considerable amounts of diesel fuel are used in connection with the distribution of our products. The 12

cost of energy sources may fluctuate widely due to economic and political conditions, government policy and regulation, war, or other unforeseen circumstances. An increase in the price of fuel and other energy sources would increase our operating costs and, therefore, could affect our profitability. The Presence of Genetically Modified Corn in Our Products, Which is Not Approved for Human Consumption, May Have a Negative Impact on Our Results of Operations As we do not grow our own corn, we are required to buy it from various producers in the United States, Mexico and elsewhere. Although we only buy corn from farmers and grain elevators who agree to supply us with approved varieties of corn and we have developed a protocol in all our operations with the exception of Venezuela to test and monitor our corn for certain strains of bacteria and chemicals that have not been approved for human consumption, we may unwittingly buy genetically modified corn that is not approved for human consumption, and use such raw materials in the manufacture of our products. This may result in costly recalls and subject us to lawsuits which may have a negative impact on our results of operations. In the past, various claims have been alleged, mostly in the United States and the European Union, that genetically modified foods are unsafe for human consumption, pose risks of damage to the environment and create legal, social and ethical dilemmas. Some countries, particularly in the European Union, as well as Australia and some countries in Asia, have instituted a partial limitation on the import of grain produced from genetically modified seeds. Some countries have imposed labeling requirements and traceability obligations on genetically modified agricultural and food products, which may affect the acceptance of these products. To the extent that we may unknowingly buy or be perceived to be a seller of genetically modified corn not approved for human consumption, this may have a significant negative impact on our financial condition and results of operation. Downgrades of Our Debt May Increase Our Financing Costs or Otherwise Adversely Affect Us or Our Stock Price Our long-term senior unsecured perpetual bond is rated BBB- by Standard & Poor s Ratings Services ( Standard & Poor s ), and BBB- by Fitch Ratings. On April 12, 2007, Standard & Poor s revised its outlook on us from neutral to negative. On February 1, 2008, Standard & Poor s placed our senior notes on Credit Watch with negative implication. On March 12, 2008, Standard & Poor s removed our senior notes from Credit Watch with negative implication after our May 2008 rights offering improved our debt ratios. We continue to have a BBB- rating with negative outlook. Our access to external sources of financing, as well as the cost of that financing, could be adversely affected by a deterioration of our long-term debt ratings. A downgrade in our credit ratings would increase the cost of and/or limit the availability of unsecured financing, which may make it more difficult for us to raise capital when necessary. If we cannot obtain adequate capital on favorable terms or at all, our business, operating results and financial condition would be adversely affected. Regulatory Developments May Adversely Affect Our Business We are subject to regulation in each of the territories in which we operate. The principal areas in which we are subject to regulation are health, environmental, labor, taxation and antitrust. The adoption of new laws or regulations in the countries in which we operate may increase our operating costs or impose restrictions on our operations which, in turn, may adversely affect our financial condition, business and results of operations. Further changes in current regulations may result in an increase in compliance costs, which may have an adverse effect on our financial condition and results of operations. See Item 4. Information on the Company Regulation. Economic and Legal Risks Associated with a Global Business May Affect Our International Operations We conduct our business in many countries and anticipate that revenues from our international operations will account for a significant portion of our future revenues. There are risks inherent in conducting our business internationally, including: general political and economic instability in international markets; 13

limitations in the repatriation of our assets, including cash; expropriation of our international assets; varying prices and availability of corn, wheat and wheat flour and the cost and practicality of hedging such fluctuations under current market conditions; different liability standards and legal systems; recent developments in the international credit markets, which could affect capital availability or cost, and could restrict our ability to obtain financing or refinance our existing indebtedness at favorable terms, if at all; and intellectual property laws of countries that do not protect our international rights to the same extent as the laws of Mexico. In addition, we have recently expanded our operations to China, Malaysia, Australia and England. Our presence in these and other markets could present us with new and unanticipated operational challenges. For example, we may encounter labor restrictions or shortages and currency conversion obstacles, or be required to comply with stringent local governmental and environmental regulations. Any of these factors could increase our operating expenses and decrease our profitability. Our Business May Be Adversely Impacted by Risks Related to Our Currency Derivatives Trading Activities From time to time, we enter into currency derivative transactions that cover varying periods of time and have varying pricing provisions. We are exposed to potential changes in the value of our derivative instruments primarily caused by fluctuations in currency exchange rates. These fluctuations may result from changes in economic conditions, investor sentiment, monetary and fiscal policies, the liquidity of global markets, international and regional political events, and acts of war or terrorism. We account for these derivative transactions using the mark-to-market accounting method. The mark-to-market value of these derivatives instruments may increase or decrease prior to the settlement date of the instruments. We may incur unrealized losses as a result of the factors described above. See Item 11. Quantitative and Qualitative Disclosures About Market Risk. Risks Relating to Venezuela Venezuela Presents Significant Economic Uncertainty and Political Risk, Which May in the Future Have an Adverse Impact on Our Operations and Financial Performance Our operations in Venezuela accounted for approximately 11% of our net sales in 2007. In recent years, political and social instability has prevailed in Venezuela. This unrest presents a risk to our business which cannot be controlled or accurately measured or estimated. For instance, as a result of the nation-wide general strike that took place from early December 2002 to February 2003, and in an effort to shore up the economy and control inflation, Venezuelan authorities imposed foreign exchange and price controls in early 2003. These price controls apply to products such as corn flour and wheat flour, which limit our ability to increase our prices in order to compensate for higher costs in raw materials. However, in February 2008, the Venezuelan government liberalized price controls on retail wheat flour. We cannot predict whether the Venezuelan government will reinstate price controls on wheat flour in the future. Additionally, the foreign exchange controls imposed by the Venezuelan government limit our ability to convert bolívares (the Venezuelan currency) into other currencies and transfer funds out of Venezuela. In February 2003, the Venezuelan government established a single fixed exchange rate for the bolívar of 1,600.00 bolívares per U.S.$1.00, which has been increased on several occasions to the current fixed exchange rate of 2,150.00 bolívares per U.S.$1.00 in effect since March 2005. Hugo Chávez, the current president of Venezuela was reelected to a second term in December 2006 and it is expected that political and social instability will continue to prevail during his six year term. Recently, the Government of 14

Venezuela announced the nationalization of foreign-owned companies in key industries such as steel, telecommunications and cement. We cannot assure you that the government of Venezuela will not continue to nationalize other foreign-owned companies. The Venezuelan government s continued nationalization of foreign owned companies could adversely affect our financial condition and results of operation. Our financial condition and results of operations could be adversely affected since, among other reasons: (i) a portion of our sales are denominated in bolívares; (ii) Gruma Venezuela produces products that are subject to price controls; (iii) part of our sales depend on centralized government procurement policies for its social welfare programs; (iv) we may have difficulties repatriating dividends from Gruma Venezuela, as well as importing some of its requirements for raw materials as a result of the exchange controls, and; (v) we may face increasing costs in some of our raw materials due to the implementation of import tariffs. Risks Relating to the United States Unfavorable General Economic Conditions in the United States Could Negatively Impact Our Financial Performance Net sales in the U.S. constituted approximately 45% of our total sales in 2007. Unfavorable general economic conditions, such as a possible recession or economic slowdown in the United States could negatively affect the affordability of and consumer demand for some of our products. Under difficult economic conditions, consumers may seek to forego purchases of our products or, if available, shift to lower-priced products offered by other companies. Softer consumer demand for our products in the United States or in other major markets could reduce our profitability and could negatively affect our financial performance. Additionally, as the retail grocery trade continues to consolidate and our retail customers grow larger, they could demand lower pricing and increased promotional programs. Also, our dependence on sales to certain retail customers could increase. There is a risk that we will not be able to maintain our U.S. profit margin in this environment. Demand for our products in Mexico, also may be disproportionately affected by the performance of the United States economy. Risks Related to Our Controlling Shareholders and Capital Structure Holders of ADSs May Not Be Able to Vote at our Shareholders Meetings Our shares are traded on the New York Stock Exchange in the form of ADSs. There can be no assurance that holders of our shares through ADSs will receive notices of shareholder meetings from our ADS depositary with sufficient time to enable such holders to return voting instructions to our ADS depositary in a timely manner. Under certain circumstances, a person designated by us may receive a proxy to vote the shares underlying the ADSs at our discretion at a shareholder meeting. Holders of ADSs Are Not Entitled to Attend Shareholder Meetings, and They May Only Vote Through the Depositary Under Mexican law, a shareholder is required to deposit its shares with a Mexican custodian in order to attend a shareholders meeting. A holder of ADSs will not be able to meet this requirement, and accordingly is not entitled to attend shareholders meetings. A holder of ADSs is entitled to instruct the depositary as to how to vote the shares represented by ADSs, in accordance with procedures provided for in the deposit agreement, but a holder of ADSs will not be able to vote its shares directly at a shareholders meeting or to appoint a proxy to do so. In addition, such voting instructions may be limited to matters enumerated in the agenda contained in the notice to shareholders and with respect to which information is available prior to the shareholders meeting. 15
